Get Edit form Controls from outside RadGrid

[Mahmoud]

Hi,

I have two related comboboxes here in Edit Form Template . and OnSelectedIndexChanged Loads the Items in the second ComboBox.

This Code works Fine on Insert Mode but on Edit Mode it Can't see the ComboBoxes ( return Nothing ):

Protected Sub CustomerName_SelectedIndexChanged(ByVal o As Object, ByVal e As RadComboBoxSelectedIndexChangedEventArgs)


        Dim editedItem As GridEditFormItem = DirectCast(rgOpportunities.MasterTableView.GetItems(GridItemType.EditFormItem)(0), GridEditFormItem)

        Dim CustomerCombo As RadComboBox = DirectCast(editedItem.FindControl("rcbCustomerName"), RadComboBox)
        Dim ContactsCombo As RadComboBox = DirectCast(editedItem.FindControl("rcbContactName"), RadComboBox)

        If (CustomerCombo.DataSourceID IsNot Nothing) Then
            CustomerCombo.DataSourceID = String.Empty
        End If
        ContactsCombo.DataSource = LoadContacts(e.Value)
        'ContactsCombo.Items.Clear()
        ContactsCombo.OpenDropDownOnLoad() = True
        ContactsCombo.DataBind()
        If ContactsCombo.Items.Count > 0 Then
            Session("ContactID") = ContactsCombo.Items(0).Value
        Else
            Session("ContactID") = ""
        End If


    End Sub

--- > CustomerCombo and ContactsCombo Access the edit form and gets the RadComboBoxes and Works Fine in InsertMode

Hello Mahmoud,

Try the following code.
C#:

protected void grid_ItemDataBound(object sender, GridItemEventArgs e)
{
 if (e.Item is GridEditableItem && e.Item.IsInEditMode)
 {
    GridEditableItem item = (GridEditableItem)e.Item;
    RadComboBox combo = (RadComboBox)item.FindControl("RadComboBox1");
 }
}

Thanks,
Princy.

Hello Princy,

I'm Sorry , That's not What I Want .

The thing is : I want to do this from SelectedIndexChanged Event Handler or from PreRender Event

because the event fired after opening edit mode . .. it means Just rhose two events will fire..

Please Help me in this..,

Hello Mahmoud,

You can access the edit form by using the Naming container property of the RadComboBox. Here is the sample code.
C#:

void list_SelectedIndexChanged(object o, RadComboBoxSelectedIndexChangedEventArgs e)
   {
       RadComboBox rdcbx=(RadComboBox)o;
       GridEditableItem editedItem =rdcbx.NamingContainer as GridEditableItem;
      //Code goes here
   }

Thanks,
Shinu.
